Hey Big sis
People that use Oxygen for a disease, respiratory or heart disease will definitely be more relaxed on the O2. They will feel short of breath off of the O2 and may feel like they are smothering, thus the panic and anxiety. For this person oxygen is the right choice.
They actually have Oxygen Bars in LasVegas where you can buy Oxygen treatment...............in flavors even. Of course there are lots of things you can do in Las Vegas.
Do you know what your oxygen blood level is......................have it checked in Drs. office with an oximeter.......if it is maintaining in low 90s, you may need some O2.
Our standard was 96-100% on room air. Unless you had a chronic lung disease and then you maybe did ok at 90%. Always individual.
